Toilet Deodorizing Apparatus

ABSTRACT

Disclosed is a toilet deodorizing apparatus having a main body controlled by a sensor switch of a control unit for discharging gases. Smell gases are guided to the inside from a gas inlet of the main body and then guided to the outside through a gas outlet to achieve a deodorizing effect.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a toilet deodorizing apparatus, andmore particularly to a main body controlled by a switch of a controlunit to guide smell gases to the inside from a gas inlet and then guidedto the outside through a gas outlet.

2. Description of the Prior Art

At present, most toilet deodorizing apparatuses available in the marketadopt a design of putting chemicals into the toilet or a design ofdiluting the concentration of smell odors. However, these conventionalapparatuses fail to meet the healthy, safety and environmentalprotection requirements or take the practicality and commercialcost-effectiveness into consideration.

The aforementioned conventional toilet deodorizing apparatus has thefollowing drawbacks:

-   1. Solid, liquid and gas chemicals are harmful to our health.-   2. Chemical deodorants may damage our water resources and    environments.-   3. The installation of an additional small bubble generator incurs a    higher cost and a more complicated structure.-   4. The smell small air bubble has a low solubility, and thus the bad    smell may still disperse into the air.

SUMMARY OF THE INVENTION

Therefore, it is a primary objective of the present invention to providea toilet deodorizing apparatus to overcome the problems of theconventional toilet deodorizing apparatus with components that can onlyeliminate or reduce the smell without any practical added-on value ofimproving the health safety, environmental protection and deodorizingfunctions.

To achieve the aforementioned objective and function, the presentinvention provides a toilet deodorizing apparatus having a main bodycontrolled by a sensor switch of a control unit for discharging gases.Smell gases are guided to the inside from a gas inlet of the main bodyand then guided to the outside through a gas outlet to achieve thedeodorizing effect.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention will be clearer from the following descriptionwhen viewed together with the accompanying drawings, which show, forpurpose of illustrations only, the preferred embodiment in accordancewith the present invention.

With reference to FIGS. 1 and 2, a preferred embodiment of the presentinvention is applied between a toilet 1 and a water tank 2. The toilet 1includes an internal sink space 11, a water outlet pipe 12, a pluralityof water outlet holes 13, a first channel 14, a second channel 15 and asewer pipe 16, wherein the water outlet pipe 12 is interconnected to theplurality of water outlet holes 13 and the first channel 14, and theinternal sink space 11 is interconnected to the sewer pipe 16, and thesecond channel 15 is interconnected to the sewer pipe 16. The water tank2 is disposed above the toilet 1 and interconnected to the water outletpipe 12 of toilet 1.

The toilet deodorizing apparatus of the present invention comprises thefollowing elements:

A main body 3 is disposed below the water tank 2 and has a gas inlet 31and a gas outlet 32, wherein the gas outlet 32 is coupled to the secondchannel 15, and the gas outlet 32 of the main body 3 is pivotallycoupled to a one-way gate 321 as shown in FIG. 4, and an exhaust pipe322 is installed between the gas outlet 32 and the second channel 15.

A control unit 40 is installed at a predetermined position inside themain body and includes a motor 41, a blower 42 and a sensor 43, whereinthe sensor 43 is provided for controlling switches of turning on or offthe motor 41 and the blower 42, and the motor 41 and the blower 42 areinstalled at opposite positions of the main body 3.

A valve 141 is pivotally installed between the water outlet pipe 12 ofthe water tank 2 and the first channel 14 of the toilet 1, and thesecond channel 15 of the toilet 1 has a insect screen 151, and the mainbody 3 is covered by a housing 21 extended from the bottom of the watertank 2, and the first channel 14 is interconnected to the housing 21.The sensor 43 of the control unit 40 is an infrared sensor for sensing ahuman body, wherein the motor 41 and the blower 42 are turned on whenthe infrared sensor 43 senses a human body. The sensor 43 of the controlunit 40 also can be a body weight sensor, wherein the motor 41 and theblower 42 are turned on when a body weight presses onto a toilet seat,or the motor 41 and the blower 42 are turned off when the body weight isreleased from the toilet seat.

With reference to FIG. 2 for a schematic view of eliminating a bad smellby suction in accordance with a preferred embodiment of the presentinvention, while water in the water tank 2 is not being used forflushing the toilet, the water outlet pipe 12 and the plurality of wateroutlet holes 13 are interconnected to the internal sink space 11 oftoilet 1, and the water outlet pipe 12 is an empty pipe. When airflow issucked into the gas inlet 31 of the main body 3 inside the housing 21,the pressure is changed to draw the smell gas from the internal sinkspace 11 of the toilet 1 through the first channel 14. Now, the valve141 droops automatically into an open status and blocks the water outletpipe 12 and draws the smell gas into the housing 21, The smell gas isthen guided to the inside from the gas inlet 31 of the main body 3, andguided to the outside from the gas outlet 32 and one-way gate 321 (asshown in FIG. 5) and finally the smell gas is discharged from theexhaust pipe 322 into the second channel 15 through the insect screen151 and entered into the sewer pipe 16.

Since the channels are sealed by the static water between the internalsink space 11 of the toilet 1 and the sewer pipe 16, therefore the waterdischarged into the sewer pipe 16 is blocked by the static water withoutproducing smell gas or overflowing to the outside of the internal sinkspace 11, so as to improve the deodorizing effect significantly, and theinsect screen 151 installed between the second channel 15 and theexhaust pipe 322 can prevent unknown living organisms inside the sewerpipe 16 from entering into the indoor space through the exhaust pipe322, so as to provide a pest control effect.

With reference to FIG. 3 for a schematic view of a suction and flushingstatus of a preferred embodiment of the present invention after thesuction stops, when the toilet 1 is flushed, water flows from the wateroutlet pipe 12 to open the originally closed valve 141 by the flushingforce. Now, the valve 141 is in a horizontal status to block the firstchannel 14 and prevent water to enter, and water flows through theplurality of water outlet holes 13 into the internal sink space 11, andnow the water outlet pipe 12 is filled up with water, and the main body3 stops operating. After the flushing ends, the suction and deodorizingoperation takes place again as shown in FIG. 2.

While we have shown and described various embodiments in accordance withthe present invention, it is clear to those skilled in the art thatfurther embodiments may be made without departing from the scope of thepresent invention.
